tain new and useful Improvements in Swinging lllindows, of which the following is a specication,V reference being had therein to the accompanying drawings.

The invention relates to metallic window sashes, and has particular reference to the construction of a window sash and the means employed for weatherprooing the same.

inthe drawings,-l*"igure l isa front elevation of a metallic window sash having a swinging section; Fig. 2 is a section on line Fig. l; Fig. 3 is a section on line Fig. l.

In the present state of the art in metallic window sash construction, it is common to form the sash from metallic bars having a T-section, the headot the T forming the outer tace of the sash and forming the ledges or rabbets in which the window panes are secured. form window sashes of this character with swinging panels arranged within the stationary portion of the sash.

l rlhe present invention is applicable to con-l structions as above described, and has for its special object the provision of a stop for the swinging sash which will eil'ectiyely weatherproof the joint in closed position.

As illustrated, is the stationary portion of a metallic window sash, and B is a swinging' panel or transom therein. Both the s tationary and swinging portions are formed of intersecting vertical and horizontal metallic T-bai's C., 'which divide the structure into a multiplicity of small panes. My improved construction of stop is applied to the adjacent bars ot the swinging and stationary sections of the sash, and is preferably formed by a metallic channel. bar D which is secured 4to the stem portion of one of the T- bais'andhas its parallel flanges projecting Specification of Letters Patent.

lt isl also common in the art to outward therefrom. These flan /esJE F are or' different length, the former ljeing adapted to abut against the inner face'of the 'l'-` head of the adjacent ban, whille the latter overlaps the stemA As shown in Fig. 2, the swinging sash above the center of pivot thereof has the stop 'barD secured thereto, flanges-of this bar abut against the adjacent rail of the stationary frame. yOn the other hand, the portion of the sash,` below the center of the pivot abuts against a stop bar D which is secured to thestationar f rail andhas its flanges E F arranged to engage with the Vhead and stem of the sash nail. At the top of the swingingsash the stop rail D2 is secured to the swinging 4sash and has its lianges abutting against the -frame, while at the botten/1l of the sash an angle bar G is secured to ,.7 the stationary frame, its flange forming an abutment or the stem portion of the sash rail; while ythe head portion'ot' said rail overlaps and abuts against the head portion of the adjacent stationary rail.` Thus, a double weather-prooling joint is formed completely around the swinging window sash. f l

Wha-tl claim as my invention is,- j ln a metallic window sash, a stationary and swinging portionjeach formed of '5&- bars or rails, and a stop or weather guard comprising (a channeled bar having its web portion secured to the stem portion of one of said 'yl-hars and its parallel 1li/anges extend- "ing outward, said flanges being of differentlengths the shorter abutting against the inner face of the head of the adjacent rail and the longenl flange abutting 'against the edge oi the stem of said rail, l
